| |
Hello.
Kill ptrace_{get,put}_breakpoints and task_struct->ptrace_bp_refcnt, 9899d11f "ptrace: ensure arch_ptrace/ptrace_request can never race with SIGKILL" made this all unneeded.
Benjamin, Paul, arch_dup_task_struct()->flush_ptrace_hw_breakpoint(src) on powerpc looks "obviously wrong". Don't we need
- flush_ptrace_hw_breakpoint(src); + dst->thread->ptrace_bps[0] = NULL;
?
Oleg.
